Lighting system comprising a master unit and slave units where the master unit can move to a sleep mode with a slave unit as a master

摘要

A system comprising a main electrical unit (2; 102) and a peripheral electrical unit (3, 4, 5; 103, 104, 105), wherein the main electrical unit (2; 102) is a control unit initially adapted for controlling the system, where the peripheral electric unit (3, 4, 5; 103, 104, 105) is adapted to be initially controlled by the main electric unit (2; 102), where the unit (2; 102) main electrical and the peripheral electric unit (3, 4, 5; 103, 104, 105) is switchable between a low energy mode and a high energy mode, wherein the main electrical unit (2; 102) is adapted to deliver the system control to the peripheral electric unit (3, 4, 5; 103, 104, 105), if the peripheral electric unit (3, 4, 5; 103, 104, 105) is in the high power mode, and to switch from high power mode to low power mode, after control has been delivered, where the unit (3, 4, 5; 103, 104, 105) Peripheral electrical is adapted to receive control of the unit (2; 102) main electrical and to control the system, if the peripheral electric unit (3, 4, 5; 103, 104, 105) is in high power mode.
